5.2.1 Usage of IR Remote
5.2.2 IR Operations
1) IR Matrix Switching
The 4 “IR OUT” ports make up a 4x4 IR matrix with the “IR IN” ports of the far-end
receivers. See as below:
Input channels, range from 1~4, IR signal switched
following HDMI signal correspondingly.
Menu buttons, AV and ALL buttons have the same
function as the front panel. THROUGH: To transfer
the signals directly to the corresponding output
channels
Example: Press “3”, “THROUGH”, the result will be IN
3OUT 3. Press “ALL”, “THROUGH”, the result will
be: 11, 22, 33, 44
Output channels, range from 1~4.
Each channel has 1 IR IN, 1 COAX, 1 HDBaseT, 1
RS232, and 1 AUDIO outputs, and channel No.1 &
No.2 has 1 HDMI output.
Standby button, press it to enter in standby mode.

Control Local Devices or MHD44TP Remotely
HDBaseT Matrix Switcher 4x4
PTN Electronics Limited 12 www.PTN-electronics.com
The IR signal is received from corresponding remote controller, then transferred to
HDBaseT receiver, then to corresponding zone of MHD44TP through the twisted pair,
finally transferred to IR OUT port and received by controlled device.
Switching Operation:
a) Sending command, reference to 5.3 RS232 Control: [x1]R[x2].
x1: Corresponding to the 4 IR OUT ports of MHD44TP, The IR emitter connected to
this port can be placed at IR receiving area of output device or MHD44TP itself.
x2: Corresponding to the zone (receive IR signal from HDBaseT receiver with IR IN
port connects with IR receiver) number of MHD44TP.
E.g.: Command “3R2.” means to transfer IR signal received from zone 2 to IR OUT
port 3.
b) Using IR remote: Input channelbutton IROutput channel
Input channel: the 4 INPUTS buttons, corresponding to the 4 IR OUT ports of
MHD44TP.
Output channel: the 4 OUTPUTS buttons, corresponding to the zone (receive IR
signal from HDBaseT receiver with IR IN port connects to IR receiver) number of
MHD44TP.
E.g.: Press buttons “3”, “IR”, “1” in order, “3” in OUTPUTS area, “1” in INPUTS area,
to transfer IR signal received from zone 3 to IR OUT port 1.
Note: When switch all the 4 IR input signal channels to a same IR out channel,
it is not able to control the controlled device(s) at the same time.
2) IR Carrier Enforcing
a) Only if the IR receiver connected with HDBaseT receiver is with IR carrier, the
received IR signal can be transferred to IR OUT port of MHD44TP.
b) Only if the IR receiver connected with IR ALL IN port of MHD44TP is with IR carrier,
the received IR signal can be transferred to IR OUT port of MHD44TP.
If the IR receiver connected with HDBaseT receiver or IR ALL IN port of MHD44TP is
not with IR carrier, you need to send the command “%0901.”, and then you are able
to transfer the IR signal to IR OUT port.
3) IR Settings
When need to control a remote displayer from local, the IR receiver used must be with
IR carrier. The IR signal is transferred to the corresponding zone connected with the
HDBaseT receiver which is connected with the IR emitter. When the IR receiver is
connected to IR ALL IN port, the IR signal can be finally transferred to all the 4 IR
emitters connected with HDBaseT receivers.
As the figure below:
13
Control Remote Displayer from Local
HDBaseT Matrix Switcher 4x4
PTN Electronics Limited 14 www.PTN-electronics.com
4) Controlled by a Third-party IR Control Device
Use the included IR converting cable (see as below), connect the red end to IR input
port of MHD44TP, the black end to IR output port of the third-party control device. Then
the IR signal is able to be transmitted via the twisted pair, and finally gets to remote
output device.
5.3 RS232 Control
5.3.1 RS232 Commands
Through the RS232 communication port, user can control a far-end device whose
bound rate is 2400, 4800, 9600, 19200, 38400, 57600 or 115200. Default setting of
MHD44TP: bound rate is 9600, data bit is 8, stop bit is 1 and parity bit is none.
